Callback Options

The callbacks are functions that will be called once an action is completed. In all of these callbacks you can retrive data sent from the Client Side using $_POST['data']`` or $_GET[‘data’]“ for the load callback. To send data from the Client Side check out Options > data

load

Called when autoloading image.

 /**
 *  @return string|array
 */
'load' => function () {
    // You can make a query from your database and return the image:
    // return '123.jpg'; |  return array('1.jpg', '2.jpg');
},

delete

Called when trying to delete image.

 /**
 *  @param  stdClass $filename
 *  @return boolean
 */
'delete' => function ($filename) {
    // Wether to allow file deletion
    return true;
},

upload_start

Called before the upload starts.

 /**
 *  @param  stdClass $image
 *  @return void
 */
'upload_start' => function ($image) {
},

upload_complete

Called after upload.

 /**
 *  @param  stdClass $image
 *  @return void
 */
'upload_complete' => function ($image) {
},

'crop_start' => function ($image) {
},

crop_complete

Called after cropping.

 /**
 *  @param  stdClass $image
 *  @return void
 */
'crop_complete' => function ($image) {
},

In all callbacks the $image parameter is an stdClass object and has the following proprieties:

• name string
• type string
• size integer (available only in upload_start)
• path string
• url string

• height integer
• versions array (available only in upload_complete and crop_complete)

You can access them like this: $image->name, $image->path.
